FIELD OF THE INVENTION

The present invention relates to a new hybrid pepper (Capsicum annuum) variety which exhibits medium high resistance to powdery mildew, resistance to Tobamovirus pathotypes P0, P1, P1-2 and P1-2-3, and a medium maturation time.

BACKGROUND OF THE INVENTION

Sweet pepper plants of the species Capsicum annuum belong to the Nightshade family, also known as Solanaceae. It is an annual herbaceous flowering plant species native to South America.

Pepper plants are being cultivated worldwide for their highly nutritious fruits. In 2007 the acreage for sweet peppers in the United States was approximately 54.3 million, with a production of about 700,000 tons (source USDA). The pepper fruits have a high vitamin A and C content, as well as a high content in dietary fiber. They are also an excellent source of Calcium. Bell peppers are eaten raw, cooked, immature and mature and may be processed into powders, sauces, and salsas. The fruits in the unripe stage are usually green, but during ripening they usually become red, although other colors are known also such as: yellow, orange, purple, white, and brown.

There are various ways of cultivating peppers, the most common are: open field, greenhouse and shade house production. Although the species can be grown under a wide range of climatic conditions, it performs most successfully under dry and warm conditions.

Powdery mildew infections in pepper caused by Leveillula taurica are becoming an increasing problem in pepper production areas. Leveillula taurica is a powdery mildew fungus capable of infecting a wide range of plant species including plants of the genus Capsicum. Symptoms of a Leveillula infection are yellow necrotic spots developing on the oldest leaves and later also on younger leaves. On the lower surface of the infected leaves white sporulating areas with abundant conidia are visible. The fungus also disrupts the hormone balance within the plant leading to abscission of also healthy leaves. The disease eventually leads to defoliation. Since managing powdery mildew epidemics with chemicals is difficult, genetically based resistances are desired.

The genus of Tobamoviruses is a group of rod shaped viruses capable of infecting a wide array of species, including Capsicum species. Pepper infecting strains of Tobamovirus are subgrouped into ‘pathotypes’, according to their reactions on a set of differential Capsicum sp. hosts. Pathotype P0 corresponds to Tobacco Mosaic virus (TMV) and/or Tomato Mosaic Virus (ToMV), Pathotype, and pathotype P1 corresponds to ToMV as well. Pathotypes P1-2 and P1-2-3 belong to isolates of Pepper Mild Mottle Virus (PMMoV). Symptoms on susceptible plants can vary considerably depending on the strain of virus, time of infection, and growing conditions. Foliar symptoms include mosaic, mottling, leaf distortion and sometimes leaf death and defoliation. Fruits of infected plants may be undersized, deformed, mottled or blotched and have a rough surface. Infected seedlings are usually stunted and pale. Tobamoviruses are easily transmitted through contact and can be transmitted by seed. Especially in greenhouse cultivation Tobamoviruses can be a problem due to the higher plant density compared to open field cultivation. Tobamoviruses are responsible for significant economic losses in pepper production areas. Genetic resistance to Tobamoviruses is thus highly desired.

Early ripening or earliness is the time needed by a cultivar to produce commercially mature fruits. Early ripening cultivars have been created through breeding in order to increase the profitability of pepper production by having earlier sales of the produce.

DETAILED DESCRIPTION OF THE INVENTION

The invention provides methods and compositions relating to plants, seeds and derivatives of a new hybrid pepper variety herein referred to as hybrid pepper variety 35-172 RZ. 35-172 RZ is a hybrid plant variety that is uniform and distinct from other such hybrids, and may be stably produced after a cycle of reproduction.

There are numerous steps in the development of any novel, plant with desirable characteristics. Selection of traits is a very important aspect of plant breeding. Once desirable traits are identified, the plants with those desirable traits are crossed in order to recombine the desirable traits and through selection, varieties or parent lines are developed. The goal is to combine in a single variety or hybrid an improved combination of desirable traits from the parent plant. These important traits may include but are not limited to higher yield, field performance, fruit and agronomic quality such as fruit shape, color and length, resistance to diseases and insects, and tolerance to drought and heat.

Choice of breeding or selection methods depends on the mode of plant reproduction, the heritability of the trait(s) being improved, and the type of cultivar used commercially (e.g., F1 hybrid cultivar, pureline cultivar, etc.). Popular selection methods commonly include but are not limited to pedigree selection, modified pedigree selection, mass selection, and recurrent selection.

The complexity of inheritance influences choice of the breeding method. Backcross breeding is used to transfer one or a few favorable genes for a highly heritable trait into a desirable cultivar. This approach is used extensively for breeding disease-resistant cultivars. Various recurrent selection techniques are used to improve quantitatively inherited traits controlled by numerous genes. The use of recurrent selection in self-pollinating crops depends on the ease of pollination, the frequency of successful hybrids from each pollination, and the number of hybrid offspring from each successful cross.

The development of commercial pepper hybrids relates to the development of pepper parental lines, the crossing of these lines, and the evaluation of the crosses. Pedigree breeding and recurrent selection breeding methods are used to develop cultivars from breeding populations. Breeding programs combine desirable traits from two or more varieties or various broad-based sources into breeding pools from which lines are developed by selfing and selection of desired phenotypes. The new lines are crossed with other lines and the hybrids from these crosses are evaluated to determine which have the desirable characteristics.

Pedigree breeding is used commonly for the improvement of self-pollinating crops or inbred lines of cross-pollinating crops. Two parents which possess favorable, complementary traits are crossed to produce an F1. An F2 population is produced by selfing one or several F1s or by intercrossing two F1s (sib mating). Selection of the best individuals is usually begun in the F2 population; then, beginning in the F3, the best individuals in the best families are selected. Replicated testing of families, or hybrid combinations involving individuals of these families, often follows in the F4 generation to improve the effectiveness of selection for traits with low heritability. At an advanced stage of inbreeding (i.e., F6 and F7), the best lines or mixtures of phenotypically similar lines are tested for potential release as new cultivars.

Mass and recurrent selections may be used to improve populations of either self- or cross-pollinating crops. A genetically variable population of heterozygous individuals is either identified or created by intercrossing several different parents. The best plants are selected based on individual superiority, outstanding progeny, or excellent combining ability. The selected plants are intercrossed to produce a new population in which further cycles of selection are continued.

Backcross breeding has been used to transfer genes for a simply inherited, highly heritable trait into a desirable homozygous cultivar or line that is the recurrent parent. The source of the trait to be transferred is called the donor parent. The resulting plant is expected to have the attributes of the recurrent parent (e.g., cultivar) and the desirable trait transferred from the donor parent. After the initial cross, individuals possessing the phenotype of the donor parent are selected and repeatedly crossed (backcrossed) to the recurrent parent. The resulting plant is expected to have the attributes of the recurrent parent (e.g., cultivar) and the desirable trait transferred from the donor parent.

Other methods of breeding may also relate to the single-seed descent procedure which refers to planting a segregating population, harvesting a sample of one seed per plant, and using the one-seed sample to plant the next generation. When the population has been advanced from the F2 to the desired level of inbreeding, the plants from which lines are derived will each trace to different F2 individuals. The number of plants in a population declines each generation due to failure of some seeds to germinate or some plants to produce at least one seed. As a result, not all of the F2 plants originally sampled in the population will be represented by a progeny when generation advance is completed.

In addition to phenotypic observations, the genotype of a plant may also be examined. There are many laboratory-based techniques available for the analysis, comparison and characterization of plant genotype; these techniques include but are not limited to Isozyme Electrophoresis, Restriction Fragment Length Polymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Amplified Fragment Length polymorphisms (AFLPs), Simple Sequence Repeats (SSRs—which are also referred to as Microsatellites), and Single Nucleotide Polymorphisms (SNPs).

Isozyme Electrophoresis and RFLPs have been widely used to determine genetic composition. Shoemaker and Olsen, (Molecular Linkage Map of Soybean (Glycine max) p 6.131-6.138 in S. J. O'Brien (ed) Genetic Maps: Locus Maps of Complex Genomes, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., (1993)) developed a molecular genetic linkage map that consisted of 25 linkage groups with about 365 RFLP, 11 RAPD, three classical markers and four isozyme loci. See also, Shoemaker, R. C., RFLP Map of Soybean, p 299-309, in Phillips, R. L. and Vasil, I. K., eds. DNA-Based Markers in Plants, Kluwer Academic Press, Dordrecht, the Netherlands (1994).

SSR technology is currently the most efficient and practical marker technology; more marker loci may be routinely used and more alleles per marker locus may be found using SSRs in comparison to RFLPs. For example, Diwan and Cregan described a highly polymorphic microsatellite locus in soybean with as many as 26 alleles. (Diwan, N. and Cregan, P. B., Theor. Appl. Genet. 95:22-225, 1997.) SNPs may also be used to identify the unique genetic composition of the invention and progeny varieties retaining that unique genetic composition. Various molecular marker techniques may be used in combination to enhance overall resolution.

Molecular markers, which include markers identified through the use of techniques such as Isozyme Electrophoresis, RFLPs, RAPDs, AP-PCR, DAF, SCARs, AFLPs, SSRs, and SNPs, may be used in plant breeding. One use of molecular markers is Quantitative Trait Loci (QTL) mapping. QTL mapping is the use of markers which are known to be closely linked to alleles that have measurable effects on a quantitative trait. Selection in the breeding process is based upon the accumulation of markers linked to the positive effecting alleles and/or the elimination of the markers linked to the negative effecting alleles from the plant's genome.

Molecular markers may also be used during the breeding process for the selection of qualitative traits. For example, markers closely linked to alleles or markers containing sequences within the actual alleles of interest may be used to select plants that contain the alleles of interest during a backcrossing breeding program. The markers may also be used to select toward the genome of the recurrent parent and against the markers of the donor parent. This procedure attempts to minimize the amount of genome from the donor parent that remains in the selected plants. It may also be used to reduce the number of crosses back to the recurrent parent needed in a backcrossing program. The use of molecular markers in the selection process is often called genetic marker enhanced selection or marker-assisted selection. Molecular markers may also be used to identify and exclude certain sources of germplasm as parental varieties or ancestors of a plant by providing a means of tracking genetic profiles through crosses.

Mutation breeding is another method of introducing new traits into pepper varieties. Mutations that occur spontaneously or are artificially induced may be useful sources of variability for a plant breeder. The goal of artificial mutagenesis is to increase the rate of mutation for a desired characteristic. Mutation rates may be increased by many different means including temperature, long-term seed storage, tissue culture conditions, radiation (such as X-rays, Gamma rays, neutrons, Beta radiation, or ultraviolet radiation), chemical mutagens (such as base analogs like 5-bromo-uracil), antibiotics, alkylating agents (such as sulfur mustards, nitrogen mustards, epoxides, ethyleneamines, sulfates, sulfonates, sulfones, or lactones), azide, hydroxylamine, nitrous acid or acridines. Once a desired trait is observed through mutagenesis the trait may then be incorporated into existing germplasm by traditional breeding techniques. Details of mutation breeding may be found in Principles of Cultivar Development by Fehr, Macmillan Publishing Company, 1993.

The production of double haploids may also be used for the development of homozygous lines in a breeding program. Double haploids are produced by the doubling of a set of chromosomes from a heterozygous plant to produce a completely homozygous individual. For example, see Wan et al., Theor. Appl. Genet., 77:889-892, 1989.

The pepper plant of the invention may be arrived at through crossing of inbred lines or through selection of the disclosed desirable characteristics by any of the breeding the selection methods mentioned above.

The breeding process which resulted in hybrid pepper variety 35-172 RZ started in 2002 by developing a mother line through 9 generations of selection and inbreeding, which resulted in a line of group 22605. The father line was developed from 2009 onward and is the result of 8 generations of selection and inbreeding, resulting in a line of group 30252. All selection steps of both the mother and father line were done in The Netherlands under glass house conditions. The F1 progeny of mother line 22605 and father line 30252 results in hybrid pepper variety 35-172.

In one embodiment, a plant of the invention has all the morphological and physiological characteristics of pepper variety 35-172 RZ. These characteristics of a pepper plant of the invention, e.g. variety 35-172 RZ, are summarized in Table 1. In table 2 the main differences with its closest publicly available variety are given.

The information presented in tables 1 and 2 was determined in trial experiments in accordance with official Dutch plant variety registration authorities (Naktuinbouw). The terminology used in these tables is the official terminology as used by the Dutch plant variety registration authorities (Naktuinbouw) as of the filing date, and is thus clear for a person skilled in the art. The terminology and testing protocol are in accordance with the official guidelines European Union Community Plant Variety Office, more specific the Protocol for Distinctness Uniformity and Stability Tests for Capsicum annuum L. (Technical Protocol 076). The person skilled in the art is familiar with the testing protocol and terminology used therein.

As used herein “medium high” resistance to powdery mildew (Leveillula taurica) means that the plant on a scale from 0-5 scores around 2. A score of “0” being completely resistant, “3” being medium resistant, “5” being completely susceptible. Screening is done on adult plants in greenhouse where spores of the pathogen have been dispersed by spraying. The infection level based on the 0-5 scale is evaluated two weeks after fruits have colored.

As used herein, resistance to Tobamovirus pathotypes P0, P1, P1-2 and P1-2-3 may be defined as the ability of the plant to grow normally after infection with Tobamovirus pathotypes P0, P1, P1-2 or P1-2-3. Screening for Tobamovirus resistance is done at first true leaf stage. The plant is inoculated by rubbing the cotyledons with a virus suspension. Identification of susceptibility is usually done after 10 days. Resistant plant are completely free of symptoms. Resistance to Tobamovirus different pathotypes is conferred by 5 alleles located on the “L” locus. Genotype reactions of the different “L” alleles are e.g. described in the official guidelines of the European Union Community Plant Variety Office (Protocol for Distinctness Uniformity and Stability Tests for Capsicum annuum L. (Technical Protocol 076) on page 29). The person skilled in the art is familiar with the testing protocol and terminology used therein.

As used herein, time of maturity is scored by visual observation of color changing, scored 2-3 times per week till fruits on 50% of the plants have changed color. The time for reaching maturity which is used as a measure earliness is defined on a scale from 1 to 9. “1” being very early, comparable to varieties Koral, Macska Sagra and Madison. “3” being early, comparable to varieties Fejer, Lady Bell, and Topgirl. “5” Being medium, comparable to varieties Lamuyo, Latino, and Sonar. “7” being late, comparable to varieties Daniel, Doux d'Espagne. “9” being very late, comparable to varieties Cancun and California Wonder. Plants of hybrid pepper variety 35-172 RZ show a medium maturation time, which is thus comparable to varieties Lamuyo, Latino, and Sonar. The skilled artisan is familiar with using such a scale for determining maturation time.

In an embodiment, the invention relates to pepper plants that has all the morphological and physiological characteristics of the invention and have acquired said characteristics by introduction of the genetic information that is responsible for the characteristics from a suitable source, either by conventional breeding, or genetic modification, in particular by cisgenesis or transgenesis. Cisgenesis is genetic modification of plants with a natural gene, coding for an (agricultural) trait, from the crop plant itself or from a sexually compatible donor plant. Transgenesis is genetic modification of a plant with a gene from a non-crossable species or a synthetic gene.

Just as useful traits that may be introduced into a hybrid by backcrossing the trait into one or both parents, useful traits may be introduced directly into the plant of the invention, being a plant of hybrid pepper variety 35-172 RZ, by genetic transformation techniques; and, such plants of hybrid pepper variety 35-172 RZ that have additional genetic information introduced into the genome or that express additional traits by having the DNA coding there for introduced into the genome via transformation techniques, are within the ambit of the invention, as well as uses of such plants, and the making of such plants.

Genetic transformation may therefore be used to insert a selected transgene into the plant of the invention, being a plant of hybrid pepper variety 35-172 RZ or may, alternatively, be used for the preparation of transgenes which may be introduced by backcrossing. Methods for the transformation of plants, including pepper, are well known to those of skill in the art.

Vectors used for the transformation of pepper cells are not limited so long as the vector may express an inserted DNA in the cells. For example, vectors which may comprise promoters for constitutive gene expression in pepper cells (e.g., cauliflower mosaic virus 35S promoter) and promoters inducible by exogenous stimuli may be used. Examples of suitable vectors include pBI binary vector. The “pepper cell” into which the vector is to be introduced includes various forms of pepper cells, such as cultured cell suspensions, protoplasts, leaf sections, and callus. A vector may be introduced into pepper cells by known methods, such as the polyethylene glycol method, polycation method, electroporation, Agrobacterium-mediated transfer, particle bombardment and direct DNA uptake by protoplasts. To effect transformation by electroporation, one may employ either friable tissues, such as a suspension culture of cells or embryogenic callus or alternatively one may transform immature embryos or other organized tissue directly. In this technique, one would partially degrade the cell walls of the chosen cells by exposing them to pectin-degrading enzymes (pectolyases) or mechanically wound tissues in a controlled manner.

A particularly efficient method for delivering transforming DNA segments to plant cells is microprojectile bombardment. In this method, particles are coated with nucleic acids and delivered into cells by a propelling force. Exemplary particles include those which may comprise tungsten, platinum, and preferably, gold. For the bombardment, cells in suspension are concentrated on filters or solid culture medium. Alternatively, immature embryos or other target cells may be arranged on solid culture medium. The cells to be bombarded are positioned at an appropriate distance below the macroprojectile stopping plate. An illustrative embodiment of a method for delivering DNA into plant cells by acceleration is the Biolistics Particle Delivery System, which may be used to propel particles coated with DNA or cells through a screen, such as a stainless steel or Nytex screen, onto a surface covered with target pepper cells. The screen disperses the particles so that they are not delivered to the recipient cells in large aggregates. It is believed that a screen intervening between the projectile apparatus and the cells to be bombarded reduces the size of projectiles aggregate and may contribute to a higher frequency of transformation by reducing the damage inflicted on the recipient cells by projectiles that are too large. Microprojectile bombardment techniques are widely applicable, and may be used to transform virtually any plant species, including a plant of pepper variety 35-172 RZ.

Agrobacterium-mediated transfer is another widely applicable system for introducing gene loci into plant cells. An advantage of the technique is that DNA may be introduced into whole plant tissues, thereby bypassing the need for regeneration of an intact plant from a protoplast. Agrobacterium transformation vectors are capable of replication in E. coli as well as Agrobacterium, allowing for convenient manipulations. Moreover, advances in vectors for Agrobacterium-mediated gene transfer have improved the arrangement of genes and restriction sites in the vectors to facilitate the construction of vectors capable of expressing various polypeptide coding genes. The vectors have convenient multi-linker regions flanked by a promoter and a polyadenylation site for direct expression of inserted polypeptide coding genes. Additionally, Agrobacterium containing both armed and disarmed Ti genes may be used for transformation. In those plant strains where Agrobacterium-mediated transformation is efficient, it is the method of choice because of the facile and defined nature of the gene locus transfer. The use of Agrobacterium-mediated plant integrating vectors to introduce DNA into plant cells, including pepper plant cells, is well known in the art (See, e.g., U.S. Pat. No. 7,250,560 and 5,563,055).

Transformation of plant protoplasts also may be achieved using methods based on calcium phosphate precipitation, polyethylene glycol treatment, electroporation, and combinations of these treatments.

A number of promoters have utility for plant gene expression for any gene of interest including but not limited to selectable markers, scoreable markers, genes for pest tolerance, disease resistance, nutritional enhancements and any other gene of agronomic interest. Examples of constitutive promoters useful for pepper plant gene expression include, but are not limited to, the cauliflower mosaic virus (CaMV) P-35S promoter, a tandemly duplicated version of the CaMV 35S promoter, the enhanced 35S promoter (P-e35S), the nopaline synthase promoter, the octopine synthase promoter, the figwort mosaic virus (P-FMV) promoter (see U.S. Pat. No. 5,378,619), an enhanced version of the FMV promoter (P-eFMV) where the promoter sequence of P-FMV is duplicated in tandem, the cauliflower mosaic virus 19S promoter, a sugarcane bacilliform virus promoter, a commelina yellow mottle virus promoter, the promoter for the thylakoid membrane proteins from pepper (psaD, psaF, psaE, PC, FNR, atpC, atpD, cab, rbcS) (see U.S. Pat. No. 7,161,061), the CAB-1 promoter from pepper (see U.S. Pat. No. 7,663,027), the promoter from maize prolamin seed storage protein (see U.S. Pat. No. 7,119,255), and other plant DNA virus promoters known to express in plant cells. A variety of plant gene promoters that are regulated in response to environmental, hormonal, chemical, and/or developmental signals may be used for expression of an operably linked gene in plant cells, including promoters regulated by (1) heat, (2) light (e.g., pea rbcS-3A promoter, maize rbcS promoter, or chlorophyll a/b-binding protein promoter), (3) hormones, such as abscisic acid, (4) wounding (e.g., wunl, or (5) chemicals such as methyl jasmonate, salicylic acid, or Safener. It may also be advantageous to employ organ-specific promoters.

Exemplary nucleic acids which may be introduced to the pepper variety of this invention include, for example, DNA sequences or genes from another species, or even genes or sequences which originate with or are present in pepper species, but are incorporated into recipient cells by genetic engineering methods rather than classical reproduction or breeding techniques. However, the term “exogenous” is also intended to refer to genes that are not normally present in the cell being transformed, or perhaps simply not present in the form, structure, etc., as found in the transforming DNA segment or gene, or genes which are normally present and that one desires to express in a manner that differs from the natural expression pattern, e.g., to over-express. Thus, the term “exogenous” gene or DNA is intended to refer to any gene or DNA segment that is introduced into a recipient cell, regardless of whether a similar gene may already be present in such a cell. The type of DNA included in the exogenous DNA may include DNA which is already present in the plant cell, DNA from another plant, DNA from a different organism, or a DNA generated externally, such as a DNA sequence containing an antisense message of a gene, or a DNA sequence encoding a synthetic or modified version of a gene.

Many hundreds if not thousands of different genes are known and could potentially be introduced into a plant of pepper variety 35-172 RZ. Non-limiting examples of particular genes and corresponding phenotypes one may choose to introduce into a pepper plant include one or more genes for insect tolerance, pest tolerance such as genes for fungal disease control, herbicide tolerance, and genes for quality improvements such as yield, nutritional enhancements, environmental or stress tolerances, or any desirable changes in plant physiology, growth, development, morphology or plant product(s).

Alternatively, the DNA coding sequences may affect these phenotypes by encoding a non-translatable RNA molecule that causes the targeted inhibition of expression of an endogenous gene, for example via antisense- or cosuppression-mediated mechanisms. The RNA could also be a catalytic RNA molecule (i.e., a ribozyme) engineered to cleave a desired endogenous mRNA product. Thus, any gene which produces a protein or mRNA which expresses a phenotype or morphology change of interest is useful for the practice of the present invention. (See also U.S. Pat. No. 7,576,262, “Modified gene-silencing RNA and uses thereof.”).

The invention further relates to propagation material for producing plants of the invention. Such propagation material may comprise inter alia seeds of the claimed plant and parts of the plant that are involved in sexual reproduction. Such parts are for example selected from the group consisting of seeds, microspores, pollen, ovaries, ovules, embryo sacs and egg cells. In addition, the invention relates to propagation material which may comprise parts of the plant that are suitable for vegetative reproduction, for example cuttings, roots, stems, cells, protoplasts.

According to a further aspect thereof the propagation material of the invention may comprise a tissue culture of the claimed plant. The tissue culture may comprise regenerable cells. Such tissue culture may be derived from leaves, pollen, embryos, cotyledon, hypocotyls, meristematic cells, roots, root tips, anthers, flowers, seeds and stems. Tissue culture methodologies relating to pepper plants are well known in the art (See generally U.S. Pat. Nos. 7,642,423 and 7,696,416). In vitro regeneration of Solanaceae cultivars is further described in Schuelter A R et al. Genet Mol.

Also, the invention comprehends methods for producing a seed of a “35-172 RZ”-derived pepper plant which may comprise (a) crossing a plant of pepper variety 35-172 RZ, representative seed of which having been deposited under NCIMB Accession No. NCIMB 42004, with a second pepper plant, and (b) whereby seed of a “35-172 RZ”-derived pepper plant forms. Such a method may further comprise (c) crossing a plant grown from “35-172 RZ”-derived pepper seed with itself or with a second pepper plant to yield additional “35-172 RZ”-derived pepper seed, (d) growing the additional “35-172 RZ”-derived pepper seed of step (c) to yield additional “35-172 RZ”-derived pepper plants, and (e) repeating the crossing and growing of steps (c) and (d) for an additional 3-10 generations to further generate “35-172 RZ”-derived pepper plants. Advantageously, a “35-172 RZ”-derived pepper plant has at least the following characteristics: medium high resistance to powdery mildew, resistance to Tobamovirus pathotypes P0, P1, P1-2 and P1-2-3, and a medium maturation time.

Backcrossing one of the parents of a hybrid may also be used to improve an inbred plant. Backcrossing transfers a specific desirable trait from one inbred or non-inbred source to an inbred that lacks that trait. This may be accomplished, for example, by first crossing a superior inbred (A) (recurrent parent) to a donor inbred (non-recurrent parent), which carries the appropriate locus or loci for the trait in question. The progeny of this cross are then mated back to the superior recurrent parent (A) followed by selection in the resultant progeny for the desired trait to be transferred from the non-recurrent parent. After five or more backcross generations with selection for the desired trait, the progeny are heterozygous for loci controlling the characteristic being transferred, but are like the superior parent for most or almost all other loci. The last backcross generation would be selfed to give pure breeding progeny for the trait being transferred.

The invention additionally provides a method of introducing a desired trait into a plant of hybrid pepper variety 35-172 RZ by reverse breeding (See generally allowed U.S. application Ser. No. 10/487,468, published as 2006-0179498 A1), which may comprise the following steps: (a) allowing the hybrid pepper plant to produce haploid cells, while suppressing recombination, (b) growing haploid cells into diploid plants, (c) selecting those homozygous plants which together constitute the hybrid variety of the invention as parent plants for the said hybrid, (d) crossing one of the said parent plants with a plant having the desired trait, (e) crossing the selected F1 progeny with said parent plant, to produce backcross progeny; (f) selecting backcross progeny which may comprise the desired trait and the physiological and morphological characteristic of the parent plant; and, optionally, (g) repeating steps (e) and (f) one or more times in succession to produce selected fourth or higher backcross progeny that may comprise the desired trait and all of the physiological and morphological characteristics of said parent plant, (h) crossing the backcrossed parent plant having the added desired trait with the other parent plant obtained after reverse breeding to obtain a plant which may comprise the desired trait and all of the physiological and morphological characteristics of a plant of pepper variety 35-172 RZ.

The invention further involves a method of determining the genotype of a plant of pepper variety 35-172 RZ, representative seed of which has been deposited under NCIMB Accession No. NCIMB 42004, or a first generation progeny thereof, which may comprise obtaining a sample of nucleic acids from said plant and detecting in said nucleic acids a plurality of polymorphisms. This method may additionally comprise the step of storing the results of detecting the plurality of polymorphisms on a computer readable medium. The plurality of polymorphisms are indicative of and/or give rise to the expression of the morphological and physiological characteristics of pepper variety 35-172 RZ.

There are various ways of obtaining genotype data from a nucleic acid sample. Genotype data may be gathered which is specific for certain phenotypic traits (e.g. gene sequences), but also patterns of random genetic variation may be obtained to construct a so-called DNA fingerprint. Depending on the technique used a fingerprint may be obtained that is unique for hybrid pepper variety 35-172 RZ. Obtaining a unique DNA fingerprint depends on the genetic variation present in a variety and the sensitivity of the fingerprinting technique. A technique known in the art to provide a good fingerprint profile is called AFLP fingerprinting technique (See generally U.S. Pat. No. 5,874,215), but there are many other marker based techniques, such as RFLP (or Restriction fragment length polymorphism), SSLP (or Simple sequence length polymorphism), RAPD (or Random amplification of polymorphic DNA) VNTR (or Variable number tandem repeat), Microsatellite polymorphism, SSR (or Simple sequence repeat), STR (or Short tandem repeat), SFP (or Single feature polymorphism) DArT (or Diversity Arrays Technology), RAD markers (or Restriction site associated DNA markers) (e.g. Baird et al. PloS One Vol. 3 e3376, 2008; Semagn et al. African Journal of Biotechnology Vol. 5 number 25 pp. 2540-2568, 29 December, 2006). Nowadays, sequence-based methods are utilising Single Nucleotide Polymorphisms (SNPs) that are randomly distributed across genomes, as a common tool for genotyping (e.g. Elshire et al. PloS One Vol. 6: e19379, 2011; Poland et al. PloS One Vol. 7: e32253; Truong et al. PLoS One Vol. 7 number 5: e37565, 2012). The polymorphism revealed by these techniques may be used to establish links between genotype and phenotype. The polymorphisms may thus be used to predict or identify certain phenotypic characteristics, individuals, or even species. The polymorphisms are generally called markers. It is common practice for the skilled artisan to apply molecular DNA techniques for generating polymorphisms and creating markers.

As mentioned earlier, known genes and alleles may be used as markers to indentify certain phenotypic characteristics, individuals, or even species. The Tobamovirus resistance alleles of the L gene present in hybrid pepper variety 35-172 RZ may be used as such (e.g. Tomita et al. MPMI, Vol. 24 Number 1, 2011, pp. 108-117). Furthermore, the resistance to powdery mildew present in 35-172 has been genotypically characterized by Lefebvre et al. (Theor. Appl. Genet, Vol. 107, 2003, pp. 661-666) using AFLPs. These markers may also assist in identifying polymorphism for the plants of the invention.

The polymorphisms of this invention may be provided in a variety of mediums to facilitate use, e.g. a database or computer readable medium, which may also contain descriptive annotations in a form that allows a skilled artisan to examine or query the polymorphisms and obtain useful information.

As used herein “database” refers to any representation of retrievable collected data including computer files such as text files, database files, spreadsheet files and image files, printed tabulations and graphical representations and combinations of digital and image data collections. In a preferred aspect of the invention, “database” refers to a memory system that may store computer searchable information.

As used herein, “computer readable media” refers to any medium that may be read and accessed directly by a computer. Such media include, but are not limited to: magnetic storage media, such as floppy discs, hard disc, storage medium and magnetic tape; optical storage media such as CD-ROM; electrical storage media such as RAM, DRAM, SRAM, SDRAM, ROM; and PROMs (EPROM, EEPROM, Flash EPROM), and hybrids of these categories such as magnetic/optical storage media. A skilled artisan may readily appreciate how any of the presently known computer readable mediums may be used to create a manufacture which may comprise computer readable medium having recorded thereon a polymorphism of the present invention.

As used herein, “recorded” refers to the result of a process for storing information in a retrievable database or computer readable medium. For instance, a skilled artisan may readily adopt any of the presently known methods for recording information on computer readable medium to generate media which may comprise the polymorphisms of the present invention. A variety of data storage structures are available to a skilled artisan for creating a computer readable medium where the choice of the data storage structure will generally be based on the means chosen to access the stored information. In addition, a variety of data processor programs and formats may be used to store the polymorphisms of the present invention on computer readable medium.

The present invention further provides systems, particularly computer-based systems, which contain the polymorphisms described herein. Such systems are designed to identify the polymorphisms of this invention. As used herein, “a computer-based system” refers to the hardware, software and memory used to analyze the polymorphisms. A skilled artisan may readily appreciate that any one of the currently available computer-based system are suitable for use in the present invention.
